Professional carpet cleaners use a hot water extractor as their main machine: a truck mount powered from the van for most homes, or a portable that plugs into the building for high-rises and offices. Around it sits a kit of an upright vacuum, a pre-spray sprayer, a CRB or orbital machine for agitation and encap, a spotter and air movers.
To use a carpet extractor, vacuum first, pre-spray the traffic lanes and let the chemical dwell, then pull the wand or machine backward in slow strokes that overlap by about 2 inches: one wet pass with the spray on, then dry passes with it off. Finish by flushing the lines with clean water and leaving the tank lids open.
Carpet usually dries in 6 to 12 hours after hot water extraction. How cleaners cut that to 3 to 6 hours with better recovery, dry passes, air movers and HVAC, and when to choose encapsulation instead.
Encapsulation carpet cleaning keeps office carpet presentable between deep cleans. How it compares with hot water extraction, how often to schedule each, and which machine your carpet maker allows.
